Ok - anyone knows what to do with the temporary redirect to the login page? In our e-commerce system we have a checkout page, which requires user to be logged in - if they are not, we redirect them to the login page using simple php header("Locaiton: url"). This however has been found as a Warning as it's a temporary redirect. I can't really put there permanent redirect for obvious reasons so if someone could give me some clue on this situation that would be much appreciated.

Can someone point me to the official article explaining why meta keywords are no longer taken into account by search engines please? I know Moz has indicated that search engines ignore them, but I would like to read a bit more about it - what was the reason behind it and since when.
